Tool uses 2D DFT and dithering to improve eInk manga quality
Original: Show HN: Using 2D DFT, dithering, etc. to maximize eInk manga image quality
A developer has shared a technique that applies a 2D discrete Fourier transform, dithering and related image processing to optimize manga pages for eInk e-readers. The work is available on GitHub under the Kindle Comic Converter project, which converts comics and manga for low-power e-ink displays. Readers and developers are discussing how signal processing can sharpen grayscale artwork on hardware with limited color and contrast.
Why now: The project was featured on Hacker News, drawing attention from e-reader enthusiasts and developers interested in image processing.
